JOHN F. AMES, OF PORTLAND, OREGON lNKlNG-PAD AND HOLDER THEREFOR.

Specification of Letters Patent.

Patented Dec. 19, 1905.

Application filed February 1'7 1905. Serial No 246,084.

To all whom it may concern:

Be it known that I, J OHN F. AMES, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented new and useful Improvements in inking-Pads and Holders Therefor, of which the following is a specification.

My invention relates to a form-inking roller and removable pad therefor for use in cylinder-presses.

In bag-making factories orders are coming in continually for bags of different sizes and shapes requiring brands of correspondinglyvarying shapes, sizes, and designs and sometimes in two or more colors. It is a matter of great inconvenience, as well as expense, if for each order or brand a new inking-roller has to be provided. Obviously there would be a great saving of time, labor, and expense to the manufacturer by having an inkingpad which could be easily taken off or put on the inking-roller to suit the exigencies of each particular case rather than having to remove and replace the entire roller.

The object of my invention is to provide a removable inking-pad and suitable holder therefor, the same holder to be used continuously in the press, while various pads may be substituted having inking-surfaces of any desired shape or size.

The invention consists of the parts and the construction and combination of parts, as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure 1 is a cross-sectionof my holderand pad arranged in operative relation to a formcylinder. Fig. 2 is an end view of the holder, showing pad applied. Fig. 3 is a side or plan view of same. Fig. 4 is a perspective view of my improved pad.

A represents the form-cylinder of a press, carrying suitable type or characters by which a brand or other printed vmatter is to be ap plied to a surface.

2 is my improved inking-pad roll or holder, carrying the removable inking-pad 3 and adapted to be driven relative to the move ment of the form-cylinder by any suitable means. The inking-pad consists of a suitable length of tough flexible material or fabric, such as heavy canvas, having the eyelets 4 at each end and provided upon one side with a suitable elastic and generally impermeable printing composition, as 5. The extent and outline of this composition will depend on the area on the form-cylinder which is to be acted upon by the inking-roller. The roller 2 is hollow and has a longitudinal peripheral slit, as 6, and suitable means are provided Within this slit for the reception of the ends of the pad 3 and for the tightening of the same around the periphery of the roller in order that the ink-applying body 5 may be properly convexed and presented to the formcylinder. In the present case I have shown the following means for attaching the pad to the holder: Along one wall of the slit 6 and within the peripheral plane of the holder are projections 7, over which the eyelets 4 in one end of the pad may be engaged. The other end of the pad is passed around the roller and into the slit and engaged with similar pins 8 on a rotary rod or shaft 9, having its ends j ournaled in the heads of the roll. One end of the rod 9 carries a ratchet 10, engaging a spring-pressed pawl 11, limiting the rotation of the rod in one direction. The other end of the rod is provided with suitable means,

as the polygonal surfaces 12, for the recep-- tion of a wrench or key by which the rod may be rotated upon the engagement of the corre sponding end of the inkingpad. This means of securing the ends of the pad allows the latter to be stretched to any desired tension around the roll and being very simple to operate admits of the quick removal and replacement of a pad at any time. Since the roller can be of any suitable diameter or length corresponding to the form-cylinder of the press with which it is asociated, an endless variety of printing-pads may be used corresponding to any size or shape of brand on the one holder.

' The invention is of particular value in multicolor-printing, since by associating two or more of these printing-rollers with the formcylinder each roller can be provided with a printing-pad having an ink-distributing surface of different shape or size, each ap lying to different areas on the impression-0y inder a different-colored ink.

The composition body 5 consists of a suitable gelatinous or gummy and elastic substance well known in the art and is cast or molded upon the canvas by suitable means, not necessary here to be described. The thickness of the elasticlayer may be approximately three-eighths of an inch. Being easily carved, it is possible to make any number of IIO these printing-pads and have them in stock as blanks, so that when an order, say, for a two-color brand of a certain size is to be run off on the press two of these pads are applied to their holders, the form on the type-cylinder inked, the inking-rollers moved into engagement with the form-cylinder, and the latter revolvedonce to produce a single impression on each pad. The portion of each pad that is to applya particular color to the brand is then outlined and the rest of the body of the ink-transferring composition is cut away. With two or more inking-rollers provided with pads of this description arranged about a formcylinder each roller would have an inking area complementing the areas of the other inking-rollers.

By employing a removable inkingpad and holder as described it is possible to use the same pads again and again in duplicating orders for customers. The same press, the same form-cylinder, and the same inking-rollers can be used to print an endless variety and sizes of brands in one or more colors.

' While I have described my invention as used particularly in conjunction with printing on fabric, it is obvious that it is applicable to a great variety of other uses; nor do I wish to be considered as limiting myself to the particular construction herein shown and described.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination with an inkingroller having a longitudinal slit, a rod near one edge of the slit and provided with pins, a row of pins along the opposite edge of theslit', and a removable inking-pad having a row of permanent eyelets along opposite edges adapted to detachably engage the aforesaid pins.

2. The combination with a roller having a longitudinally-extending slit, a rod journaled in the roller and extending along one edge of the slit, and provided with pins, a row of inwardlyeXtending pins along the opposite edge of said slit, an inking-pad including a flexible sheet having a row of permanent eyelets along opposite edges, said sheet having an elastic ink-distributing composition upon its outer surface and said eyelets adapted to detachably engage said pins, and means whereby the rod may be rotated to stretch the sheet over the face of the roller.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
